Title: Seamless belt
Inventor: OTA HIROAKI
IPC: B29C41/04
Filed: 1989-06-21
Abstract: PURPOSE:To obtain a seamless belt with good peeling property, long life, simple and low cost by performing centrifugal molding of a mixed resin contg. a thermosetting resin or elastomer, a lubricant powder and a volatile solvent and forming an agglomerated layer of the lubricant powder on the surface. CONSTITUTION:A seamless belt is formed by performing centrifugal molding of a mixed resin contg. a thermosetting resin or elastomer, a lubricant powder and a volatile solvent and forming an agglomerated layer of the lubricant powder on the surface of the belt by utilizing the difference in specific gravities of the base resin and the lubricant powder. The agglomerated layer 2 is formed on the outer surface of the base resin 1. When a fluorinated resin powder with a large specific gravity is used as the lubricant powder and in addition, a conductive carbon is incorporated in the mixed resin, by performing centrifugal molding of this mixed resin, a fluorinated resin layer 2A is formed on the outer surface of the base resin 1 and a conductive carbon layer 3 is formed on the inside thereof. Said seamless belt having the conductive carbon layer 3 is especially effective as a belt for electrostatic recording.
